Nadhim Zahawi: My hon. Friend is absolutely right that we take this step confidently but cautiously. I remind the House that this is probably the most infectious respiratory virus known to humankind, with aerosol transmission, so we need to ensure that we are careful as we head into step 4. I outlined the action that we are taking on key workers and critical workers, and of course the police fall within that.

Nadhim Zahawi: And volunteers and the police. The hon. Member for Rhondda (Chris Bryant) reminds us all of the role that policemen and women played in ensuring that the vaccination roll-out worked well. The very clear guideline is that we should take both personal and corporate responsibility. It is great to see Transport for London, other transport systems and the M10 of metro Mayors, which I speak to regularly, taking that corporate responsibility. We all have our part to play, as we have done by coming together and vaccinating the country at scale. This is the most infectious respiratory disease that is aerosol-transmitted. We have to be very careful to ensure that we take this step carefully; for it to be irreversible, we have to continue to work together with a booster campaign. Beyond that, in the years to come, we have to get used to the transition from pandemic to endemic status.
